A uniform stationary ladder of length L = 4.2 m and mass M = 19 kg leans against a smooth vertical wall, while its bottom legs rest on a rough horizontal floor. The coefficient of static friction between floor and ladder is μ = 0.38. The ladder makes an angle θ = 53° with respect to the floor. A painter of mass 8M stands on the ladder a distance d from its base.
a. Find the magnitude of the normal force N, in newtons, exerted by the floor on the ladder.
b. Find an expression for the magnitude of the normal force NW exerted by the wall on the ladder.
c. What is the largest distance up the ladder dmax, in meters, that the painter can stand without the ladder slipping?

Problem 21: A uniform stationary ladder of length L = 3.7 m and
mass M = 19 kg leans against a smooth vertical wall, while its
bottom legs rest on a rough horizontal floor. The coefficient of
static friction between floor and ladder is μ = 0.44. The ladder
makes an angle θ = 56° with respect to the floor. A painter of mass
8M stands on the ladder a distance d from its base.

1) A ladder whose length L is 12 m and mass m are 45 kg rests
against a wall. Its upper end is a distance h of 9.3 m above the
ground. The center of mass of the ladder is one-third of the way up
the ladder. A fire fighter whose mass M is 72 kg climbs the ladder
until his center of mass is halfway up. Assume the wall but not the
ground is frictionless. What forces are exerted...

A uniform ladder of length L and mass m leans against a
frictionless vertical wall, making an angle of 57° with the
horizontal. The coefficient of static friction between the ladder
and the ground is 0.42. If your mass is four times that of the
ladder, how high can you climb before the ladder begins to
slip?

A uniform ladder of length L and mass m leans
against a frictionless vertical wall, making an angle of 55° with
the horizontal. The coefficient of static friction between the
ladder and the ground is 0.40. If your mass is four times that of

A thin, uniform bar of length L and mass M is suspended
horizontally at rest. It is suddenly released
and, at the same instant, it is struck a sharp blow vertically
upwards at one end – the duration of
the impulse is negligibly short.
